Application filed September 20, 1919. Serial No. 325,080.

To (1.1/1 w/iom it may concern.

it known that we. Bnxnmo'r WOLTER' and Amish) C. lhzown. of Book Island, in,

the county of Rock island and State of Till-l I have invented certain new and usefulv )roveiuents do hereby declare the following to be a| u clear, and exact descripti n of the in-} use the same. 7

Our object is to improve upon that class l iices adapted to apply lubricating oili from a street railway car to the guard rails at curves in the tracks. I We provide oiling devices mounted upon a; l portion of the car truck preferably ad ja elltvvo opposite wheels. Each device es an oil; chamber and a shoe con- -30 stantly saturated with the lubricant. The

: o of the wheel and track due to friction.

Figure 1 is a sectional view of one of the oil ng devices, parts being in side elevation. p 2 is a plan view of the actuating means on the car body.

li e have shown the oiling device mounted upon a rigid frame 1 forming part of the car truck so that it will be constantly maintained in fixed bodily relation to the wheel 2 The oiling device consists of a chamber 5 adapted to contain the lubricant and formed at its lower end with a hollow neck l at the extremity of which is a shoe 5 adapted to lie adjacent the inner face of the wheel flange. WVe especially seek to avoid transmitting the oil to the tread surface of the wheel, resulting in slippery tracks. We aim to supply it only to the inner face of the liange which contacts with the guard rails at the curves of street railway lines.

Within the neck at is absorbent material 6 such as cotton waste. A screen 7 prevents this material from working into the oil chamber. The shoe is provided with a pad 8 in contact with the absorbent material. 5 Thus the oil is free to feed from the chamber 8 through screen 7 and the absorbent on, such as will enable others skilled int the art to which appertains to make and! material 6 to the pad to maintain the shoe constantly saturated.

We have shown the neck at swiveled upon a post 9 rigid on frame 1. This evenly balances the weight of the oiling device as an in 'lrack-Lubricators; andrlentirety. A pin 10 is received by the post and provided with a fixed ring 12 movable in a groove formed in the post. This tends to promote the even balance.

The pin 10 pro ects from a thlckened surface 13 on the under face of the neck and between this sur- A spring 15 shown secured to the post 9 and to the base of the oil chamber normally holds the shoe of the oiling device out of ontact with the wheel.

j To automatically effect the contact of the shoe with the wheel we provide the following instrumentalitiesz The under face of the car body is provided with two arcuate spring plates 16, 17, oppositely disposed and each having one end secured to the car body and the other end free. A shaft 18 of substantially T-shape is rigidly secured to the oiling device. It is shown extending vertically from the neck 4:. Its lateral arms l9, 20, are adapted for engagement with the contiguous spring plates 16, 17 as the car truck turns on its swivel connection with the car body when traveling over a curve. illustrated the lateral arm 19 lies contig uous to spring plate 16 and arm QO'is adj acent plate 17. Thus whether the car turns to the right or left, and the truck carrying the oiler follows the curvatureof the track and turns'on its swivel, one of the arms 19 or will contact with its spring plate and the oiling device will beturned against the tension of spring 15 to effect contact betweenthe shoe 5 and the car wheel. As the var reaches a straight track and the truck alines with the body the spring plate will dieengage the arm and spring 15,will remove the shoe from the wheel. The action of the yielding spring plates prevents sudden jars that might break or derange the parts.

We preferably employ two of the described apparatus, onefor each front wheel of the forward truck.

We claim as our invention:

1. Means for automatically lubricating ace and the top of the post is a bearing 4mg 1%. 4

railway tracks, comprising a car truck and tiguous a car wheel, with means for maintaining a constant supply of oil from said chamber to said shoe, means tending to hold said shoe out of contact With said wheel when the car is traveling on a straighttrack, 7

a pair oi arcuate spring plates carried by the car body, and a shaft fixedly secured to said oiling device and having a pair of lateral arms adapted'to be engaged by said plates as the car turns to the right or left to turn said oiling device, and cause said shoe to engage the Wheel. 7

2. In an apparatus of the character described, the combination with a car body having a pair of arcuate spring plates oppositely disposed and each secured at one end and having its other end free, of an oiling means-c scribed, the combination with a car truck having an oiling device swiveled thereon, and a T-shaped shaft fixed to said oiling device, of a car body having a pair of plates adapted to engage the lateral arms of said shaft when the car is traveling upon a curve to render said oiling device effective.

4-. In an apparatus of the character described, the combination With a car truck having a fixed frame member, a post secured thereon, an oiling device comprising an oil chamber, a shoe, and an intermediate neck swiveled upon said post, and a T-shaped shaft extending vertically from said neck, of a car body having a pair of plates adapted to engage thelateral arms of said shaft when the car is traveling upon a curveto render said oiling device effective.

In testimony \vherof We have signed this specification.
